Varying curvature of a form when adding edge

[cali.season26]

Hi,

The Sculpt form tool is pretty useful, but I found some cons using it :

1 - when I add a merge, the surface is varying. Why ?

  I minimize the numbers of edge, when I create a form, prefering to densify the numbers of edges, where I need them.

But adding an edge, the surface then twisting or buckling.

It is really awkward.

2 - when I add an edge, there is a preview of the edge, it's very nice, but the added edge is NEVER at the place of the preview.

Why is this gap ?

Just for kidding ?

For question 1-  adding geometry will change the way the surface is defined, and thus the shape.  These edges are not anything like edges on a model in "model" mode.  If you want the shape to stay the same when adding edges, change insertion mode to "exact."  This will add additional edges as necessary to maintain the geometry.  Of course, this makes the model more dense and complicated, so this option is usually not used.

for question 2-

when you are in smooth mode, you are looking at the end result of the calculations done on the control edges/vertices.  to see these, change to box mode (alt 1).  In box mode, adding edges does put the edges exactly where you place them.  They off course move when switch back to smooth mode (alt 3).

You can simply consider this behavior as maintaining the smoothness as F360 see fits
